On a newer 1996-up OBD2 vehicle, a loose or bad gas cap can cause the check engine light to come on. some cars yes everyone should have a shop manual for their vehicle, and the library should have a professional shop manual(wiring diagrams and more detailed info) available in the reference section for FREE....make copies of the right sections, and fix it like a PRO!! good luck Dave :)

No, it will not.
A clogged or defective fuel filter will very likely cause a check engine light. If it is suspected, it should be replaced.
Yes, it is possible.
If the fuel pressure is too low that might cause the service engine light to come on and , since there would not be enough fuel pressure, might also cause a sluggish response. That could be caused by a clogged fuel filter also.

In thew tank right by the filler hole , just look in tank with a flash light.
Using contaminated fuel can cause an engine misfire which will turn on the check engine light. A faulty gas cap can for sure turn on the light.
According to the Owners Manual (See "Related Questions" below), that indicates the gas tank cap needs to be checked - likely not tightened enough. Check fuel cap Momentarily illuminates when the ignition is turned to the ON position to ensure your bulb is working. When this light turns on, check the fuel filler cap. Continuing to operate the vehicle with the check fuel cap light on, can activate the Service Engine Soon/Check Engine warning light. When the fuel filler cap is properly re-installed, the light(s) will turn off after a period of normal driving. This period will vary depending on driving conditions. It may take a long period of time for the system to detect an improperly installed fuel filler cap. For more information, refer to Fuel filler cap in the Maintenance and care chapter.
Usually, but not always.

No, but a defective fuel cap can set the "check engine" light to come on.
It could be fuel pump, fuel filter or out of fuel. To be certain, you can always use a code scanner to see if there are any stored codes.
A frail fuel line can cause a diesel engine not to start.
No, a loose gas cap can cause the check engine light to come on but not the low fuel light.
A bad fuel cap can make your check engine light go on. It shouldn't cause your car to run rough or die.

According to my 2004 Jetta owner's manual, that's the fuel filler cap indicator: " A warning light in the instrument cluster will come on if the fuel filler cap is not properly closed. If the warning light comes on, you should turn off the engine and close the fuel filler cap properly. Once the cap is properly closed all the way, the warning light will go out when the ignition is turned on again and the check cycle is complete. The completion of the check cycle depends on how you drive. If the awarning light has been on for at least 5 minutes, it will go out only when the ignition is turned off and on again."
Possibly. Replace the fuel filter to see if that solves your problems.
No, it will cause a check engine light along with fuel economy and power issues.
That would one of hundreds of possible causes.
If the check engine light is on for a 95 Lincoln town car, check the computer codes. a problem could cause low fuel economy, or cause a part failure over time.
